0324ffc5d5 Fix PEM certificate loading that sometimes fails
As described in https://github.com/openssl/openssl/issues/9187, the
loading of PEM certificates sometimes fails if a line of base64
content has the length of a multiple of 254.
The problem is in get_header_and_data(). When such a line with a
length of 254 (or a multiple) has been read, the next read will
only read a newline. Due to this get_header_and_data() expects to be
in the header not in the data area. This commit fixes that by checking
if lines have been read completely or only partially. In case of a
previous partial read, a newline will be ignored.

Move some ASN1 struct typedefs to types.h

Update ParseC to handle this.  Most of all, ParseC needed to be more
consistent.  The handlers are "recursive", in so far that they are called
again and again until they terminate, which depends entirely on what the
"massager" returns.  There's a comment at the beginning of ParseC that
explains how that works. {Richard Levtte}

de0799b0fc PEM: constify PEM_write_ routines
There's no reason why the object to be written, or the key string
given by the caller should be non-const.

This makes the IMPLEMENT_PEM_..._const and  DECLARE_PEM_..._const
macros superfluous, so we keep them around but mark them deprecated.

In all places where IMPLEMENT_PEM_..._const and  DECLARE_PEM_..._const
are used, they are replaced with the corresponding macros without
'_const'.

25f2138b0a Reorganize private crypto header files
Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:

While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.

To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:

  #include "internal/file.h"      # located in 'include/internal'
  #include "internal/file_int.h"  # located in 'crypto/include/internal'

This commit moves the private crypto headers from

  'crypto/include/internal'  to  'include/crypto'

As a result, the include directives become unambiguous

  #include "internal/file.h"       # located in 'include/internal'
  #include "crypto/file.h"         # located in 'include/crypto'

hence the superfluous '_int.h' suffixes can be stripped.

The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.

0cd1b144f9 util/mkerr.pl: make it not depend on the function code
The output C code was made to use ERR_func_error_string() to see if a
string table was already loaded or not.  Since this function returns
NULL always, this check became useless.

Change it to use ERR_reason_error_string() instead, as there's no
reason to believe we will get rid of reason strings, ever.

To top it off, we rebuild all affected C sources.

a1df06b363 This has been added to avoid the situation where some host ctype.h functions
return true for characters > 127.  I.e. they are allowing extended ASCII
characters through which then cause problems.  E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably.  Likewise letters with diacritical marks can also cause problems.

If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.

The implementation uses a single table with a bit for each of the defined
classes.  These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set.  They will
work for both signed and unsigned character inputs.

    -Rename DRBG_CTX to RAND_DRBG, etc.
